The following will be automated shortly
Run above script on a clean Ubuntu 16.04 VM (you may need to set your hostname in /etc/hosts)
Login to port 8880
select existing onap kubernetes environment
Add your host - run the docker agent pasted to the gui
Wait for the Kubernetes CLI to provide a token, copy past this to ~/.kube/config
Experimental Installation
Rancher 2.0
see https://gerrit.onap.org/r/#/c/32037/1/install/rancher/oom_rancher2_setup.sh
./oom_rancher2_setup.sh -s amsterdam.onap.info
Run above script on a clean Ubuntu 16.04 VM (you may need to set your hostname in /etc/hosts)
The cluster will be created and registered for you.
Login to port 80 and wait for the cluster to be green - then hit the kubectl button, copy paste the contents to ~/.kube/config
